One way to unlock this achievement start the game up and when you reach the main menu go onto V-Rally Mode once there hit RB and get to the Dealers panel and select the V-Rally Cross now select the first car which should be the Renault Alpine A310 and select Test and It once it loads select Start race now you can drift around the map all while accumulating a drift total of 1000m
If you have already bought the first car you can continue to do it with the next cars.
I also recommend drifting in circles.
